MATTHEW J. FLANNERY, OF CHICAGO, ILLINOIS.

CAR-DOOR.

Specification of Letters Patent.

Patented Dee. 16, 1919.

Application led January 24, 1919. Serial No. 272,917.

To all whom it may concern.'

Be it known that I, MArrHEw J. FLAN- NERY, a citizen of the UnitedStates, residing at Chicago, in 'the county of Cook and State ofIllinois, have invented new and useful Improvements in Car-Doors, ofwhich the following is a specication.l

This invention relates to railway freight car doors, and moreparticularly to doors used on cars which are employed for hauling grain.

The invention has for its object to provide a strong and simple door ofthe kind stated, and also one which can be readily opened, and which,when it is closed, is securely held in this position.

The object stated is attained by means of a novel combination andarrangement of parts to be hereinafter described and claimed, and inorder that the same may be better understood, reference is had to theaccompanying drawing forming a part of this specification.

In the drawing,

Figure 1 is an elevation of the door viewed from the outside of the car;

Fig. 2 is an enlarged section on the line 2 2 of Fig. 1;

Fig. 3 is an enlarged section on the line 3-3 of Fig. 2, and

Fig. 4 is a detail in latch member.

Referring specifically to the drawing, the door is composed of a seriesof superposed sections 5 positioned inside the car wall 6 and extendinghorizontally across the usual door opening 7 lined on its sides with jamb posts 8. The bottom section seats on the Hoor of the car. Each doorsection is reinforced by cross pieces 9 secured to its outer face, andby blocks 10 secured to its inner face, the former being positioned tocome inside the jam-b posts 8 as shown in Fig. 2. The door sections arepositioned back of the jamb posts 8.

The inner faces of the jamb posts 8 are lined by strips 11 on whichl arefastened the Shanks 12 of hooks 13, one pair for each door section 5.The outer ends of the shanks project from the jamb posts, and are shapedto form the hooks, the latter extending laterally of the shanks andbeing located opposite the ends of the door sections.

The blocks 10 have recesses 14 opposite the hooks 13 to house pivotedspring clip members 15. The clips have hook-shaped ends perspectiveshowing a 16 adapted to engage the hooks 13, similar to latches and saidhooks 13 therefore serve as keepers for the latches. To each clip orlatch member is connected a releasing chain 17, having a ring 17a at itsouter end said ring being located on the outside of the block 10. A pullon the chain 17 from the inside of the door, by means of the ring 17a,disengages the latch member 16 from the keeper 13.

The outer face of each door section 5 is fitted with rings 18 forfacilitating handling.

To open the door, the uppermost section 5 is slid upward until the latchhooks 16 slip olf the keeper hooks 13. The top section is now free andmay be dropped into the car or on the material therein so as to be outof the way and allow the next section to be pushed upward, and so onuntil all or as many sections as desired have been removed. If-the topsection cannot be conveniently reached, a crow bar or other suitabletool may be applied to the bottom section of the door and all thesections slid upward until the latches are disengaged. An entrance tothe car having been gained, the door on the other side of the car may beopened by drawing on the chains 17 to release the latches. It will benoted that the latch devices do not lock the door sections but merelyserve to prevent the same from Vdropping rearwardly into the car.Outward displacement of the door sections is prevented by their seatingat their ends against the same posts 8, and a lateral displacement isprevented by the cross pieces 9 and the jamb posts 8.

I claim:

The combination with a car wall having a door opening; of a doorcomposed of a series of sections slidably supported in superposedrelation across the opening and against outward displacement, latchdevices at the ends of the sections for holding the same against inwarddisplacement, keepers for the latch devices on the car wall, said latchdevices and their keepers being inside the car, and the latch devicesbeing pivoted for engagement with and disengagement fromthe keepers, andbeing also disengageable when the door sections are slid, and meanslocated inside the door for releasing the latch devices.

In testimony whereof I aflix my signature.
